Do any ChronoLogic USB devices offer isolation?
Yes. All ChronoLogic USB Instruments offer isolation between the PC and devices under test. This is extremely important for instrumentation but only a few vendors offer this as standard. Isolation is critical for prevention of ground loops that can occur when distributed devices are grounded at multiple points. Ground loops result in slight voltage offsets and can inject noise into the measurement equipment or the device under test. Furthermore isolation protects both the PC and attached devices. A significant voltage can exist across the ground potential in a distributed measurement environment. Inadvertent connection of these differing potentials can cause damage not only to the PC and USB device, but also any equipment connected to the network.
